Hydantoin-containing polythiol compositions: Hydantoin-containing polythiol compositions. Morgan, Charles R. (Grace, W. R., and Co., USA). U.S. US 4020086 26 Apr 1977, 11 pp. Division of U.S. 3,945,982. (English). (United States of America). CODEN: USXXAM. CLASS: IC: C07D233-72. NCL: 260309500. APPLICATION: US 74-461207 15 Apr 1974. DOCUMENT TYPE: Patent CA Section: 36 (Plastics Manufacture and Processing) Compns. curable with free radical catalysts or actinic radiation were prepd. from a polyene and a polythiol, both derived from a hydantoin glycol, e.g. N,N'-bis(2-hydroxyethyl)dimethylhydrantoin (I) [26850-24-8]. Thus, 959.4 g trimethylolpropane diallyl ether (II) [682-09-7] and 1000 g isophorone diisocyanate (III) [4098-71-9] were stirred 4.5 h at 70.degree. and 48 h at 24.degree.. Pentaethoxylated I (301.3 g) was added dropwise to 535 g II-III reaction product contg. 16 drops stannous octoate at <70.degree. to give an unsatd. monomer. I 432, mercaptopropionic acid [107-96-0] 445, and p-toluenesulfonic acid 17.5 g in 100 ml ethylene dichloride were heated 8 h at 71-5.degree. while removing water to give the polythiol monomer. Unsatd. monomer (49.2 g) and 30.0 g polythiolmonomer contg. photosensitizer and stabilizers were polymd. 2 min with UV radiation to give a polymer having elongation at failure 133% compared with .ltoreq.90% for polymers prepd. with the unsatd. monomer and com. polythiols.

Fatty and benzoic acid esters of ethoxylated hydantoins substituted or not in the 5-position: Fatty and benzoic acid esters of ethoxylated hydantoins substituted or not in the 5-position. MacFadyen, Donald Edward (Glyco Chemicals, Inc., USA). U.S. US 4028378 7 Jun 1977, 14 pp. (English). (United States of America). CODEN: USXXAM. CLASS: IC: C07D233-72. NCL: 260309500. APPLICATION: US 73-419497 27 Nov 1973. 64554-62-7 which is the cas registry number is also used here. DOCUMENT TYPE: Patent CA Section: 36 (Plastics Manufacture and Processing) Section cross-reference(s): 28 Fatty and benzoic acid esters of ethoxylated hydantoins, useful as plasticizers and lubricants for plastics, were prepd. Thus, 426 g com. oleic acid (80-8% total oleic acids) was treated with 174 g com. 1,3-bis(.beta.-hydroxyethyl)-5,5-dimethylhydantoin [26850-24-8] 8 h at 220.degree. to give a product with OH no. <10 and acid value <5. The reaction mixt. was cooled to 70.degree. and deodorized with 0.2% of its wt. of 35% H2O2 to give the fatty acid ester with acid value 2.9, OH value 9.5, and sapon. value 155.4. .
